The old acousticblackmetal.org hosting has expired and the domain has become possessed by lukewarm posers.
I wasn't running the old site, so I don't have backups of anything other than the Nyhetsvarsel site. Send me a message here if you want an account for your site.
Hail the Necrowizard!
I'll send you the Inverted Necromancer stuff as soon as I can gather it, if I don't recall wrong, the old webmaster was Xaphiris, you could try contacting him, though I lost his email.
This old blog still survives, where Count Raven and I had uploaded some albums, you can recover those in the meantime:

Hail the Necrowizard!
All the links on that site are dead. I've got 2 Inverted Necromancer albums uploaded. I'll make a new post with all the stuff now.
